The utility model provides an aerator anti-winding device which comprises an anti-winding main body, a driving mechanism and a transmission lifting mechanism, and the length of the anti-winding main body is larger than the
minimum distance between suspension chain aerators at the two ends of the same floating
pipe at the
pool bottom. The anti-winding main body is provided with a through hole capable of vertically penetrating through a
branch air
pipe connected with a suspension chain aerator and has a degree of freedom of relative sliding relative to the
branch air
pipe of the suspension chain aerator, the transmission lifting mechanism comprises a synchronous belt and a lifting
rope, the driving mechanism is in transmission connection with the synchronous belt, and the lifting
rope is connected with the lifting
rope. The upper end of the lifting rope is fixed to the synchronous belt through a conveying guide support, and the lower end of the lifting rope is fixed to the anti-winding body. According to the technical scheme provided by the utility model, the
workload of taking out the external counterweight piece from the
sewage treatment tank is greatly reduced, the cleaning and maintenance efficiency of the
aeration system is remarkably improved, the
water treatment progress of the
sewage treatment tank is further improved from the side surface, and the device is suitable for being widely popularized and applied in the technical field of
water aeration devices.
